We already know that Justin Bieber is incredibly competitive on the basketball court. Just ask Maroon 5 singer Adam Levine, who said on late night TV earlier this summer that he and The Biebs engaged in a little shoving during a good-natured game of hoops. Well, The Biebs stepped back onto the court and squared off with his 'Baby' partner, rapper Ludacris. But this time, it was for a good cause.

Rap-Up reports that Luda's annual celebrity basketball game took placed during "LudaDay Weekend" -- get it?! -- and unfolded at Morehouse Gym at Forbes Arena in Atlanta on Sunday, Sept. 4. The Bieb teamed up with Shawty Lo, Sean Garrett, and Kevin Durant and they went on to taste victory via a narrow defeat of Team Luda, the roster of which was filled out by Chris Paul, Carmelo Anthony, and Teyana Taylor. Team Biebs won by a mere two point margin, as the final score tallied 134-132. Congrats to The Biebs and his teammates for pulling out the win.

The Biebs tweeted about the game on Sunday, writing: "felt great winning 2day. felt even better knowing we did it 4 #charity. thanks 2 all the fans who came out 2 support."

When all was said and done, and all the hoops were shot and free throws completed, a total of $10,000 was raised for charity. Nice work, gentlemen.
